This document describes a proposed methodology for using learning analytics to quantify and improve skills development and attainment in large classes. It presents an algorithmic approach that analyzes assessment scores and other student data to generate reports on course outcomes attainment. The methodology is demonstrated through an example that shows the percentage of average attainment for each outcome in a sample course and identifies outcomes that need more focus based on the number of students above or below certain attainment levels. The goal is to provide quantitative feedback to help instructors plan lessons, assessments, and improvements based on skills attainment data.

Application of Higher Education System for Predicting Student Using Data mini...AM Publications
The aim of research paper is to improve the current trends in the higher education systems to understand
from the outside which factors might create loyal students. The necessity of having loyal students motivates higher
education systems to know them well, one way to do this is by using valid management and processing of the students
database. Data mining methods represent a valid approach for the extraction of precious information from existing
students to manage relations with future students. This may indicate at an early stage which type of students will
potentially be enrolled and what areas to concentrate upon in higher education systems for support. For this purpose
the data mining framework is used for mining related to academic data from enrolled students. The rule generation
process is based on the classification method. The generated rules are studied and evaluated using different
evaluation methods and the main attributes that may affect the student’s loyalty have been highlighted. Software that
facilitates the use of the generated rules is built which allows the higher education systems to predict the student’s
loyalty (numbers of enrolled students) so that they can manage and prepare necessary resources for the new enrolled students.

Higher learning institutions nowadays operate in a more complex and competitive due to a high demand from prospective
students and an emerging increase of universities both public and private. Management of Universities face challenges and concerns of
predicting students’ academic performance in to put mechanisms in place prior enough for their improvement. This research aims at
employing Decision tree and K-means data mining algorithms to model an approach to predict the performance of students in advance
so as to devise mechanisms of alleviating student dropout rates and improve on performance. In Kenya for example, there has been
witnessed an increase student enrolling in universities since the Government started free primary education. Therefore the Government
expects an increased workforce of professionals from these institutions without compromising quality so as to achieve its millennium
development and vision 2030. Backlog of students not finishing their studies in stipulated time due to poor performance is another
issue that can be addressed from the results of this research since predicting student performance in advance will enable University
management to devise ways of assisting weak students and even make more decisions on how to select students for particular courses.
Previous studies have been done Educational Data Mining mostly focusing on factors affecting students’ performance and also used
different algorithms in predicting students’ performance. In all these researches, accuracy of prediction is key and what researchers
look forward to try and improve.

The data of curriculum quality evaluation based on students evaluation of teaching contains learners perception of curriculum quality is helpful to provide reference for the improvement of curriculum quality. The evaluation system of curriculum quality should be built around ten evaluation dimensions, such as teaching objectives, subject frontier, case teaching, teacher literacy, classroom discussion, teaching methods, teaching courseware, information technology, teachers Q and A, curriculum ideological and political. Taking the students of school of physics and electronic information of Nanchang Normal University as the research object, and the sample size of curriculum quality evaluation is 5443, the Pearson correlation analysis is carried out on ten evaluation dimensions, and the correlation coefficient is 0.770, which indicates strong positive correlation. A regression model with ten evaluation dimensions as independent variables and curriculum satisfaction as dependent variables is established. The resolution of the model is 77.4 , which can predict curriculum satisfaction, and which has theoretical support for teachers to pay attention to the curriculum quality and improve the curriculum quality. It emphasizes that teaching department should pay attention to the effect of evaluation results on the continuous improvement of curriculum quality. It is suggested that a substantial and effective mechanism for continuous improvement should be established.

Fuzzy analysis for assessment of river water qualityeSAT Journals
Abstract
River water gets polluted due to rapid industrialization and urbanization with inadequate cognizance to the implementation of pollution control measures. Due to asymmetric occurrence of pollutants at various locations of the river the environmental impact assessment (EIA) has an important role in defining river water quality. At present experts are facing lots of problems to decide for a proposed development project based on the laboratory test results only. Because no tool are available to them which can give precise information or knowledge for taking best decision in favour of the project except the process of EIA[4,6]. But in EIA, most of the parametric information or data are not always crisp or precise rather linguistic and hedges viz. “good discharge”, “less turbidity”, “high pH”, “low BOD”, etc. to list a few only out of infinity. All such type of data are fuzzy in nature naturally evaluation of such fuzzy data is not possible with numerical valued description. As human beings every decision-maker hesitates more or less on every evaluation activity because some part of his evaluation contributes to truthness, some part to falseness and rest part may be indeterministic to him[3]. So uncertainty is the great problems to an experts while taking any decision. In this paper a methodology of Fuzzy EIA has been studied using the logic of Intuitionistic Fuzzy Set (IFS)[1] theory for assessment of river water quality with degree of certainty.

Retinal blood vessel extraction and optical disc removaleSAT Journals
Abstract Retinal image processing is an important process by which we can detect the blood vessels and this helps us in detecting the DIABETIC RETINOPATHY at a early stage and this is very helpful because the symptoms are not known by anyone unless we have blur eye sight or we get blind. And this mainly occurs in people suffering from high diabetes. So by extracting the blood vessels using the algorithm we can see which blood vessels are actually damaged. So by using the algorithm we can continuously survey the situation and can protect our eye-sight. Keywords: field of view, retinopathy, thresholding, morphology, Otsu's algorithm, MATLAB.

Perspective of biodiesel & solar pv as a combined renewable energy system...eSAT Journals
Abstract The power generation method is more over traditional and supply of electricity is decentralized which is considered a single line technology based on limited supply devoid of considering rural consumer’s point of view. The main aspect of this paper is to propose the best possible outcome as a combined power system for rural electrification from a combination of renewable resources to complete the electrical demands in a consistent manner of an off grid remote village Bakri, in the district of Jhenaidah, Bangladesh. Renewable energy resources namely solar photovoltaic cell and bio-diesel generators are considered here. The paper estimates the residential demand in the pre HOMER analysis. Using simulation software named HOMER scrutinizes the maximum outcome. It also clarifies that our proposed combine power system is cost effective techno-economically & environmentally sound and last but not the least sustainable. Here HOMER observes a number of simulations and gives us a set of systems for rural electrification requirement of 147 kWh/d and 10kW peak load.

Product aspect ranking using domain dependent and domain independent revieweSAT Journals
Abstract
In today’s world, internet is the main source of information. There are many blogs and forum sites available where people discuss on different issues and also almost all ecommerce website provide facility to the users to express opinion about their product and services which is important information available on the internet .The problem with this information is that this reviews are mostly not organized therefore creating difficulty for knowledge acquisition. There are many solution exist to resolve this problem but the available existing methods depends on extracting product aspect only considering single domain relevant review corpus. To address this problem, a method is explored to identify product aspect from online review is by taking into account the difference in aspect statistical characteristic across different corpus. This paper shows need of automatically identifying important product aspects from available online customer review and an approach of aspect ranking. This paper also shows the related work on this domain. Our methodology confirmed product aspect which are less nonspecific in domain independent corpus and more domain specific. Then customer opinion expressed on these aspects is determined using sentiment classifier and finally ranking of product aspect is calculated using it’s ranking relevance score of each aspect . Keywords— Product aspect, aspect ranking, sentiment classification, customer review, opinion mining, aspect identification, product ranking.

Abstract Human society is entering an era of ubiquitous computing, when networks are seamlessly interconnected and information is always accessible at our fingertips. In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Red Tacton is emerging technology that enables the first practical HAN (Human Area Network)between body-centered electronic devices and PCs or other network devices embedded in the environment via a new generation of user interface based on totally natural human actions such as touching, holding, sitting, walking, or stepping on a particular spot. By making Human Area Networks feasible, Red Tacton will enable ubiquitous services based on human centered interactions and therefore more intimate and easier for people to use. Red Tacton is a break-through technology that uses the surface of the human body as a safe, high speed network transmission path. So we, in this paper are explaining the unique new functional features and enormous potential of Red Tacton as a Human Area networking technology. Technology is making many things easier; we can say that our concept is standing example for that. So far we have seen LAN, MAN, WAN, INTERNET & many more but here is new concept of “RED TACTON” which makes the human body as a communication network.

Abstract The boundaries of multiverse are almost infinite and so the thirst of mankind for latest technology .man has startled many principles of space and nature by gaining them facing all fatal difficulties. Time is one quantity which is considered to be fast happening, but when it comes to happenings in space it is faster. All what we look into space is past; under least possible cases we could see the present. So, there has a necessicity for us to keep a big eye on making our search for extra-galactic recourses or extra-celestial life forms etc with equal speeds of space time. for this to be achieved by us we need to make some drastic changes in our telescope usage and we have to adopt technological up gradation and we should no longer make our telescope concentrate on the same celestial body for days continuously , indeed mili seconds should be enough to grab the required information .

Speaker identification system using close seteSAT Journals
Abstract The present paper describes experiments conducted to evaluate the performance of speaker recognition. The experiments conducted using Neural Network shows that the complexity of speaker recognition increases when the numbers of speakers to be identified are large in numbers in the text independent situation. In the first experiment error rate was zero for 10 speaker’s classification and performance was good. By increasing the number of speakers the error rate increased, classification and performance were poor. After 25 speakers, the error rate was very high. For 100 speaker’s classification MATLAB NN tool did not support for display the confusion matrix. To overcome this problem the second experiment has been done. In this experiment a close set of 10 groups of 100 speakers (each group of 10 speakers) in terms of cell array in MATLAB has been defined and we observed that the best result of speaker identification was 100% in 20 continuous features of speaker’s voice, but it increased time complexity. In the third experiment speaker’s dialect and regions were also identified and classification performance was 100% at 97 epochs, validation performance was 0.0035046 at 91 epochs and the error rate was zero has found. Index Terms: text dependent, text independent, speaker identification, Neural Network, close set, MFCC, Speaker identification, close set.
Numerical analysis of heat transfer in refrigerant flow through a condenser tubeeSAT Journals
Abstract In this thesis, heat transfer analysis of refrigerant flow in a condenser tube has been done. The main objective of this thesis is to find the length of the condenser tube for a pre-defined refrigerant inlet state such that the refrigerant at the tube outlet is saturated liquid or sub cooled liquid. The inlet refrigerant condition is saturated vapor. The problem involves refrigerant flowing inside a straight, horizontal copper tube over which air is in cross flow. Inlet condition of the both fluids and condenser tube detail except its length are specified. Here, changing pressure at discrete points along the tube is calculated by using two-phase frictional pressure drop and momentum equation mode. The heat transfer calculation has done by using condensation heat transfer correlations and simple heat transfer equations. The inside heat transfer coefficient calculated by using two phase heat transfer coefficient correlation. The unknown length of condenser tube has discrete many numbers of small elements. Each and every element has a calculations based on the pressure drop as well as heat transfer based on those correlation and every element calculated properties of refrigerant values has to check its states. At end of the iteration, a last element has reached saturated liquid condition of refrigerant and stops the entire calculation. So the length of condenser tube has been calculated by number of iteration and number of nodes with its distance. Predicted values were compared using another condensation heat transfer correlations. A computer-code using Turbo C has been developed for performing the entire calculation. Keywords: Heat transfer, Refrigeration, Multi phase flow, condenser flow, Tube length
Performance improvement of bottleneck link in red vegas over heterogeneous ne...eSAT Journals
Abstract In communication networks, congestion avoidance in routers is one of the hottest topics. Current IP network has become the dominant paradigm for all networking environments. The significant cause of packet losses in such heterogeneous networks is no longer limited to network congestion. Traditional TCP interprets every packet loss as caused by congestion which may be not the case in the current Internet. TCP Vegas detects network congestion in the early stage and successfully prevents periodic packet loss that usually occurs in TCP Reno. In this paper a new variant of TCP Vegas namedRed Vegas has used. The Red Vegas may detect random packet losses precisely. Through the packet loss differentiation, Red Vegas reacts appropriately to the losses, and therefore the throughput of connection over heterogeneous networks significantly improved. The bandwidth of the bottleneck link is under-utilized when the random loss rate is high. Therefore, a new design of the fast recovery mechanism for Red Vegas would be carried out. The proposed mechanism improves the aggression of Vegas TCP in competing for the available bandwidth whilst maintaining the inherent stability of the original Vegas TCP scheme.

Abstract
Now days, Customer feedback and satisfaction is playing a significant role in commercial product to market. Customer can be reviewed by other customer feedback and collect all the relevant information related to a particular product. Based on that the decision can be taken to purchase the product. In the traditional method, Random forest predicted the impact of the review but not worked with segmentation on the basis of multiple reviewer comments. At the same time, the variable cluster algorithm has been addressed in the market segmentation for retailing the customer’s lifestyle. It has been provided with the segmentation method, but not guide to full proof strategies for different product decision. Instead of that to guide different customers with a variety of product feedback using pattern mining approaches. The product review pattern mining segmentation based on probabilistic principle component analysis is proposed. The opinion mining, segments has categorized into several segments with pattern analysis based on multiple review comments. This mechanism has reduced the dimensionality of the segmentation process using the covariance matrix approach. The experiment uses the opinion rank review dataset information for further process. It increases the segmentation efficient upto9% when compare with traditional and conventional methods. The experimentation has been done with the important factor of opinion decision threshold, false positive rate, segmentation efficiency and customer product ratio level along with customer behavioral feedback.

Design of a wind power generation system using a permanent magnet synchronous...eSAT Journals
Abstract This paper presents a wind power system using a Permanent Magnet Synchronous Machine (PMSM). The whole system consists of a wind turbine, a permanent magnet synchronous machine, a three phase diode rectifier, a boost converter, a transformer-less step down circuit, an H-bridge inverter and a T-LCL filter. The 3-phase AC output from the PMSM is sent to the 3-phase diode rectifier for conversion to DC and a boost regulator is used to step-up this DC voltage to the desired level. This step-upped DC voltage is then converted into AC output by the H-Bridge inverter. The switching technique of the proposed inverter consists of a combination of Sinusoidal Pulse Width Modulation (SPWM) and a square wave along with grid synchronization conditions. As the suggested method is entirely transformer-less, it significantly reduces Total Harmonic Distortion (THD) to less than 0.1% and minimizes its size. The T-LCL Immittance Converter not only reduces the harmonics of the inverter output but also provides a nearly constant output current thereby stabilizing the system. The system setup and the simulation results were obtained using the PSIM software. Keywords: Wind Turbine, Permanent Magnet Synchronous Machine, Boost Converter, Step- down Circuit, T-LCL Immittance Converter, Inverter

Abstract
Mostly 5 to 15% of the women in the stage of reproduction face the disease called Polycystic Ovarian Syndrome (PCOS) which is the multifaceted, heterogeneous and complex. The long term consequences diseases like endometrial hyperplasia, type 2 diabetes mellitus and coronary disease are caused by the polycystic ovaries, chronic anovulation and hyperandrogenism are characterized with the resistance of insulin and the hypertension, abdominal obesity and dyslipidemia and hyperinsulinemia are called as Metabolic syndrome (frequent metabolic traits) The above cause the common disease called Anovulatory infertility. Computer based information along with advanced Data mining techniques are used for appropriate results. Classification is a classic data mining task, with roots in machine learning. Naïve Bayesian, Artificial Neural Network, Decision Tree, Support Vector Machines are the classification tasks in the data mining. Feature selection methods involve generation of the subset, evaluation of each subset, criteria for stopping the search and validation procedures. The characteristics of the search method used are important with respect to the time efficiency of the feature selection methods. PCA (Principle Component Analysis), Information gain Subset Evaluation, Fuzzy rough set evaluation, Correlation based Feature Selection (CFS) are some of the feature selection techniques, greedy first search, ranker etc are the search algorithms that are used in the feature selection. In this paper, a new algorithm which is based on Fuzzy neural subset evaluation and artificial neural network is proposed which reduces the task of classification and feature selection separately. This algorithm combines the neural fuzzy rough subset evaluation and artificial neural network together for the better performance than doing the tasks separately.

Performance evaluation of indian business schools using the mahalanobis taguc...eSAT Journals
Abstract Grading is a competitive philosophy adopted by many institutions to attract the academic aspirants. Contemporary grading tools are designed to evaluate the institutions status of their performance and success. Generally, the required data is available in multidimensional form for getting the present status of the institutions. However, more multivariate data analysis methods are available for solving these systems, but most of these methods provide analysis based on some statistical assumptions. In this work, the complementary methodology is proposed for the analysis, which will provide a quantitative measure of the B-Schools performances. The proposed Mahalanobis Taguchi System (MTS) based methodology is a pattern information technology developed by Dr.Taguchi. This method is aimed at providing better prediction ability for multidimensional data through the construction of a multivariate measurement scale. Subsequently, the useful variables under this study are identified using the Orthogonal Arrays and Signal-Noise ratio. This study the Indian B-School data with four variables and four classes are use for this analysis.

Global advancements, competitions and economic growth have lead to a drastic change in the technological world. The impact of technology both individually as well as collectively changed our life significantly. Nomatter whether it is commercial, transportation, banking, political, or educational field technology has done wonders in all ways. With the leaps and bounds in technological field educationists still make efforts towards new achievement and goals especially in the field of teaching-learning worlds also. If we talk about today’s classroom conditions, we are still lagging behind in many aspects. We are not upto mark or update. So there is a need of adoption and inclusion of ICT and technology resources to be linked to our curriculum system. The role of teacher is quite important in molding shape of our coming generations and modern society. The teacher should make use of innovative devices and strategies while teaching in the classroom situations. The teaching-learning without innovations and technological based devices is meaningless unless we strengthen our whole educational system in terms of technology-based teacher’s professional development through in-service or pre-services trainings, incorporation of latest electronic gadgets and devices in teaching-learning system etc. Thus, this paper focus on the universal design for learning practices for classroom testing and assessment practices, which is designed to minimize errors, adverse consequences, and unintentional actions to assist students in using them safely and efficiently. This paper has directed about the perceptions about the usability of web sites addressing technology which includes the new technologies, approaches, strategies and techniques to be adopted in the classroom for strengthening the potential and competencies of the students. The main objectives of the paper are- (1) To find out the latest techniques, tools and technology based on the classroom assessment and resources. (2) To find out the usability of the websites addressing new technologies and strategies. (3) To make students understand about technological usage for enhancing motivation and feedback thereby reducing errors and mistakes. For this research paper, the researcher consulted various conceptual research frameworks, reviews and trends in studies related to the use of web-sites enhancing technologies, strategies, equipments and resources. The results of the study highlighted major concerns in order to monitor the technology proficiency of the students, one must use multiple methods for presenting the instruction; use multiple assessment formats and tools to support one towards academic progress. Thus, the teachers, educators, stakeholders all have to monitor the technology-based curriculum process supporting assessment and evaluation tools, techniques and resources.
Assessment and Evaluation System in Engineering Education of UG Programmes at...ijtsrd
Assessment is one of the most critical dimensions in engineering education process it focuses not only on identifying how many of the predefined education goals and objectives outcomes have been achieved but also works as a feedback component for educators to upgrade their teaching practices. The assessment can be seen as a link that it forms with other education processes. Lamprianou et al. 2009 point out that assessment is associated with the educational objectives of "evaluation, diagnosis, guidance, selection, placement, administration, prediction or grading. Assessment is one main factors that contribute to a high quality teaching and learning environment and student's performance as whole. It also makes clearer what teachers expect from students Biggs et al., 1999 . The perceived difficulty in this process is how assessment system, approaches and schemes can be standardized and adapted across the premier institutes NITs of in the country. Credit system has been used widely by many HEIs in India for over 20 years but no nationally agreed and rationalized framework of credit and Credit Transfer and Accumulation System is developed. The purpose of the literature review is to outline research studies in the assessment and evaluation systems being practicedand to highlight the studies that can be used in the research project undertaken. Specifically, the literature review attempts to address the following research questions What researches are undertaken nationally and internationally into the assessment system in higher education, especially engineering education What are the key findings from these researches What are the limits delimitations of these researches Are there research findings could be applied to engineering education at UG in NITs in India Are there any prime concern for future research in this area From this literature review, it is apparent that a very few number of studies have been conducted in higher education institutions but no research was found in the context of Engineering Education specific to UG programmes and NITs. However, many innovations are on the way to improvise the assessment and evaluation mechanisms in the engineering education especially in the context of Outcome Based Education OBE . J. P.

ow-a-days data volumes are growing rapidly in several domains. Many factors have contributed to this growth, including inter alia proliferation of observational devices, miniaturization of various sensors ,improved logging and tracking of systems, and improvements in the quality and capacity of both disk storage and networks .Analyzing such data provides insights that can be used to guide decision making. To be effective, analysis must be timely and cope with data scales. The scale of the data and the rates at which they arrive make manual inspection infeasible. As an educational management tool, predictive analytics can help and improve the quality of education by letting decision makers address critical issues such as enrollment management and curriculum Development. This paper presents an analytical study of this approach’s prospects for education planning. The goals of predictive analytics are to produce relevant information, actionable insight, better outcomes, and smarter decisions, and to predict future events by analyzing the volume, veracity, velocity, variety, value of large amounts of data and interactive exploration.

Abstract
The objective of the present study is to understand about all the problems occurring in the company because of improper application
of material management. In construction project operation, often there is a project cost variance in terms of the material, equipments,
manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore,
if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking
corrective actions towards the cost variance. Therefore a methodology is used to diagnose and evaluate the procurement process
involved in material management and launch a continuous improvement was developed and applied. A thorough study was carried
out along with study of cases, surveys and interviews to professionals involved in this area. As a result, a methodology for diagnosis
and improvement was proposed and tested in selected projects. The results obtained show that the main problem of procurement is
related to schedule delays and lack of specified quality for the project. To prevent this situation it is often necessary to dedicate
important resources like money, personnel, time, etc. To monitor and control the process. A great potential for improvement was
detected if state of the art technologies such as, electronic mail, electronic data interchange (EDI), and analysis were applied to the
procurement process. These helped to eliminate the root causes for many types of problems that were detected.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Laboratory investigation of expansive soil stabilized with natural inorganic ...eSAT Journals
Abstract
Soil stabilization has proven to be one of the oldest techniques to improve the soil properties. Literature review conducted revealed
that uses of natural inorganic stabilizers are found to be one of the best options for soil stabilization. In this regard an attempt has
been made to evaluate the influence of RBI-81 stabilizer on properties of black cotton soil through laboratory investigations. Black
cotton soil with varying percentages of RBI-81 viz., 0, 0.5, 1, 1.5, 2, and 2.5 percent were studied for moisture density relationships
and strength behaviour of soils. Also the effect of curing period was evaluated as literature review clearly emphasized the strength
gain of soils stabilized with RBI-81 over a period of time. The results obtained shows that the unconfined compressive strength of
specimens treated with RBI-81 increased approximately by 250% for a curing period of 28 days as compared to virgin soil. Further
the CBR value improved approximately by 400%. The studies indicated an increasing trend for soil strength behaviour with
increasing percentage of RBI-81 suggesting its potential applications in soil stabilization.
Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Influence of compaction energy on soil stabilized with chemical stabilizereSAT Journals
Abstract
Increase in traffic along with heavier magnitude of wheel loads cause rapid deterioration in pavements. There is a need to improve
density, strength of soil subgrade and other pavement layers. In this study an attempt is made to improve the properties of locally
available loamy soil using twin approaches viz., i) increasing the compaction of soil and ii) treating the soil with chemical stabilizer.
Laboratory studies are carried out on both untreated and treated soil samples compacted by different compaction efforts. Studies
show that increase in compaction effort results in increase in density of soil. However in soil treated with chemical stabilizer, rate of
increase in density is not significant. The soil treated with chemical stabilizer exhibits improvement in both strength and performance
properties.

Experimental investigation on circular hollow steel columns in filled with li...eSAT Journals
Abstract
Composite Circular hollow Steel tubes with and without GFRP infill for three different grades of Light weight concrete are tested for
ultimate load capacity and axial shortening , under Cyclic loading. Steel tubes are compared for different lengths, cross sections and
thickness. Specimens were tested separately after adopting Taguchi’s L9 (Latin Squares) Orthogonal array in order to save the initial
experimental cost on number of specimens and experimental duration. Analysis was carried out using ANN (Artificial Neural
Network) technique with the assistance of Mini Tab- a statistical soft tool. Comparison for predicted, experimental & ANN output is
obtained from linear regression plots. From this research study, it can be concluded that *Cross sectional area of steel tube has most
significant effect on ultimate load carrying capacity, *as length of steel tube increased- load carrying capacity decreased & *ANN
modeling predicted acceptable results. Thus ANN tool can be utilized for predicting ultimate load carrying capacity for composite
columns.

Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.
Keywords: Flat slabs, punching shear, unbalanced moment.

Estimation of surface runoff in nallur amanikere watershed using scs cn methodeSAT Journals
Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different
land use/land cover and with different soil conditions.
Keywords: Watershed, Nallur watershed, Surface runoff, Rainfall-Runoff, SCS-CN, Remote Sensing, GIS.

Effect of variation of plastic hinge length on the results of non linear anal...eSAT Journals
Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted. Keywords: Pushover analysis, Base shear, Displacement, hinge length, moment curvature analysis
Effect of use of recycled materials on indirect tensile strength of asphalt c...eSAT Journals
Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.
Keywords: Reclaimed asphalt pavement, Foundry waste, Recycling, Marshall Stability, Indirect tensile strength.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract
The intervention of technology in the teaching and learning processes is bringing change. There is requirement of methods and
techniques to analyze the generated data in these processes. Traditional way of delivery and assessment is becoming more
focused by the application of technology. In this paper, we propose and illustrate an algorithmic methodology that shall allow the
stakeholders in education to focus more on skills attainment effectively.
In large size class, there is huge data generated by registration system, administration system, and the learning management
system together. We propose the methodology that mainly maps and quantizes the learning outcomes, and that relates to the
successful and weaker range of attainments of stakeholders. This algorithmic methodology reads the data viz. course details,
outcomes, and assessment scores of a large class and analyzes the skills attainment with respect to the planned each course
outcome. The detailed report is generated with the average of attainment of the class strength, highest attainment, and lowest
attainment in each of the course outcomes for each student.
Key Words: Learning Analytics, Software tool, System Architecture, Course Outcomes, and Skills Attainment
--------------------------------------------------------------------***----------------------------------------------------------------------
1. INTRODUCTION
Accreditation agencies in the world have outlined the
required attributes of engineering graduates. The attributes
are eventually mapped to the contents of curriculum that
helps in the attainment and in the development skills of
graduates.
Identifying and addressing good and weak attainment
groups especially in large size student classes is a challenge
to the Instructors. With the help of emerging educational
data mining technologies and learning analytics, it is
becoming feasible for focusing effectively more on learning
outcomes. Analytics of data in course management will help
in redesigning the course outcomes. It will produce
quantized evidence for new assessment tools and
implementations.
The delivery of contents is planned by Instructors in various
forms. There are challenging decisions on curriculum,
instruction, assessment strategies, monitoring the student
performance, etc. The decision making is challenging
especially when the size of class is large. Following
parameters if are considered for analyzing then the
challenges become even more formidable”:
(a) Monitoring performance of each stakeholder,
(b) Addressing and identifying the groups that needs
attention,
(c) Averaging the performance over various electives in
different semesters, etc.
(d) Predicting optimal performance,
(e) Planning and redesigning effective course instructions,
(f) Designing, testing, and evaluating the course contents
and relevant resources, and
(g) Identifying the appropriate assessment tools and
techniques.
This motivates the design of an algorithmic solution that
shall facilitate the collecting, presenting, and analyzing the
academic, learning, assessment, data to the meet various
objectives.
2. LITERATURE SURVEY:
Techniques used in analyzing various engineering domains
exist widely in literature. The importance of analytics is
grown recently after proliferation of management
information systems in everyday life. There are various
categories of analytics based on domains, e.g. health
analytics in health care, learning analytics in universities,
business analytics in communication, insurance, and
banking systems.
Learning Analytics [1, 2] is defined as “the measurement,
collection, analysis and reporting of data about learners and
their contexts, for purposes of understanding and optimizing
learning and the environments in which it occurs.”
In order to address the applications of technology in
education, this context requires use of learning analytics.
The usage shall help in decision making at Institute or
administrative level, faculty level, and student level. Some
of the useful gains (not all covered) of applying learning
analytics are: increased productivity, effective resource
allocations, transformation pedagogical approaches,
provides interventions to risk learners, and help to students
in gaining the insight on own learning.

The online courses are reshaping with advent of technology.
Traditional courses are getting transformed with addition of
growth of tools and frameworks. In order of make learning
effective especially in large classes, it essential to focus on
parameters that shall help in planning lessons, resources,
assessments, and delivery of the course in the class.
There are efforts [3, 4, 6-18] in various directions to capture
the data and apply effectively in order to improve learning.
An e-learning tool [3] based on object oriented approach
wherein objects are text, audio, and graphics. Upon request
from student the tool dynamically creates customized course
based on profile in the learning management system. There
are other tools [19, 28-30] in the learning and academic
analytics that aid in management of courses.
There are various approaches and methods on delivering
contents [4-6]. The delivery methods [4] are transmitted to
remote learning management system, which provides the
contents, based on request from users. The focus is more on
delivering automatically transmitting the contents to remote
learning management system, and maintaining/ updating
automatically the course catalog. The Academic Analysis
Tool [7] is the software that analyzes student behavior
which actually gives the feedback on how students use and
learn in different courses.
There are applications and methods [20-27] of academic
analytics, which are applied for future predictions, and also
some other cases [32-36] of applying analytics in literature
are available.
3. SYSTEM ARCHITECTURE BASED ON ‘LIFE
CYCLE OF SUCCSSIVE SKILLS
ATTAINMENT’
Learning in the classroom has life cycle that aims at
attainment of skills. The components of cycle are: mainly
the learner’s interaction with instructor, content lessons,
assessment tools, and the skills attainment. This is iterative
cycle of improvement with duration of semesters and years.
The target course outcomes that are derived and planned
from the program outcomes are set based on graduate
attributes. On the basis of target outcomes, the content
lessons are delivered for learning. Schematic outline
showing the life cycle on successive skills attainment is
depicted in FIGURE 1. The content lessons include the
resource material, books, videos, etc. The cycle is iterative
and it improves on growth in learning, helps in taking
decisions on delivery, planning, and understanding the
delivery contents.
FIGURE 1: Life Cycle of Successive Skills Attainment
We have implemented the system architecture that will
allow focusing on skills improvement and the attainment by
using learning analytics. The methodology quantizes and
maps the parameters of interest especially assessment and
delivery of course contents. There is flexibility of defining
and planning the different assessment sequences and
weightages. The models built on these defined course
assessment tools provide results on the attainment of each
planned outcome.
FIGURE 2 depicts the system architecture with the layout of
components and its implementation. Following are the
analytical modules or components used in the system
architecture:
Assessment Design Module
Course Outcomes Module
Report Generation Module
Learning Analytics Module
There two main interactive modules: one for designing
course outcomes and another for designing various types of
assessments. The program outcomes are mapped to course
outcomes requires to be entered, as it forms the basis of
performance evaluation.

Volume: 03 Issue: 10 | OCT-2014, Available @ http://www.ijret.org 360
FIGURE 2: System Architecture of Implementation
The course outcomes while being entered are verified with
Bloom’s Taxonomy, and this will be providing the
classification of each design outcome. This will help in
balancing the outcomes in learning of course. The intelligent
course design module shall advise the classification and also
will give short-comings as feedback to the design process.
The process of entering data, classifying outcomes
statements is completely independent of course contents or
the subject matter. The process implementation is automated
with an algorithmic solution. Automated weighted
assessment in the design module is implemented with an
algorithmic methodology. It allows defining the weightage
of each assessment in the final computation of performance.
This is useful when there are multiple assessment tools
applied for continuous evaluation.
The learning analytics module and the report generation
module are designed with an algorithmic methodology that
provides:
(a) Average attainment of each course outcome,
(b) The list of highest attainment group,
(c) The list of lagging or weak attainment group,
(d) The complete attainment report in excel sheet and
portable document format, and
(e) The record of average attainment in each case of
program outcome based on multiple mapped courses.
In the next section we shall illustrate the details of the
methodology by running input on sample course.
4. ILLUSTRATIVE EXAMPLE
In this section we shall demonstrate the implementation
of the methodology on sample input course. The system
architecture and methodology is tested over 50 courses
in real life with each course containing 3 examinations
and its corresponding laboratories.
FIGURE 3 shows the percentage of average attainment
of each course outcome for the Course Title: Theoretical
Computer Science, Course Code: CT-202, Semester IV,
with 82 students.
FIGURE 3: Percentage of average attainment of each
course outcome
It is clear from the percentage of average course outcomes
attainment that course outcome CO 3 is highest; while as
course outcome CO 1 and CO 5 attainment needs attention,
and accordingly the planning for the lessons to strengthen
further.
TABLE 1 shows the course outcomes attainment with
number of students achieving with 75% and above and the
lagging behind on 35% and below. For example the course
outcome CO 2 has 8 students lagging behind by score 9.88
% or below.
TABLE 1: Course outcomes attainment with number of
students
The course outcomes CO 1 and CO 5 have 5 and 7 students
respectively with attainment of 75% or above. The number
of students with lagging behind in the attainment of course
outcomes CO 1 and CO 5 is more. This cyclic feedback
shall help in planning the lessons, in designing outcomes,
and in adoption of the next assessment tools and methods.
5. DISCUSSION
The algorithmic implementation demonstrates an illustration
of iterative cycle of improving the skills attainment. The
presented methodology quantifies the attainment and
provides the detailed reports. By analyzing the generated
reports it is feasible to address the weaker groups with
respect to the outcomes.
In future there is also need to quantify and map the iterations
for benchmarking excellence in courses. The feedback of the
iterations shall bring the improvements in each step of the
learning process.
